Other Parts Discussed in Thread: BQSTUDIO,
Can't find any document, which specifies timeouts after those operations:
- seal
- unseal
- rom mode enter
- rom mode exit
I just found in the "Updating the bq275xx Firmware at Production" document that there should be a 250 ms delay after ROM mode exiting. But the *df.fs file (got it by reading bq27520-g4 via bqStudio) has a 4000 ms delay. So, what is the correct value?
One more question. Should I seal device after successful updating? I think, so, but diagrams in the document above doesn't show that.
